Step-by-step explanation:
Draw a rectangle. If the length is 3 inches longer than its width, we can write the width as "w" and the length as the width + 3
Area is (width)(Length) = (width)(width+3)
W
----------

| |
| | L = w+3

-----------
A = (w+3)(w)
A = w2 + 3w = 108.
(Problem states that area is 108 sq in)
Need to solve this quadratic equation
w2 + 3y - 108 = 0
Factor:
(w - 9) (w + 12) = 0
So
w - 9 = 0. or. w + 12 = 0
Solve these and get
w = 9. or. w = -12
Only one that makes sense in real life is the poitive one.
So the dimensions are
Width = 9 inches
Length = 12 inches
Answer: Here are a few ways that you could apply expressions or equations to a camping trip.
The cost of renting a cabin could be: C = 50N + 70, where C is the cost and N is the number of nights.
The number of tents needed could be: T = P/3, where T is the number of tents and P is the number of people going.
The amount of marshmallows needed could be: M = 5P, where M is the number of marshmallows and P is the number of people.
Answer:
60 minutes
Step-by-step explanation:
3 hours = 180 minutes
180 - (50 + 40 + 30) = 180 - 120 = 60
